application filed 'Qctoberfi, 1925. Serial 1%. cam.

My invention'relates to pocket knives and I hereby declare the followingwhen' taken in connection with the accompanying drawings and characters of reference marked thereon, to be a clear, full and correct 'description of the same.

fThe object of the invention is to produce" a pocket knife of simple construction com-. prising buttwo main parts which'are eco nomical to manufacture and convenient and eflicient in use, 7 U I The invention isfurther characterized in that it includes a handle; portion adapted to be made of a single piece of wire bent into shape to provide a housing for the sides and edge of "the blade and to provide a spring for the blade, the said wire handle portion being adapted to be bent up 1nto shape by an automatic machine thus insuring an extremely low cost of manufacture beside producing a durable, simple, con-- venient and efficient pocket knife.

WVith these and other objects in view the invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and; pointed out in the claims hereto appended, t- 'being understood that various changes in the form proportion, size and minor details of construction within the scope of the claims may be resorted to without departure from thespirit or sacrificing any of the advantagesof the invention.

Similar characters of reference denote like or corresponding parts throughout the several figures of the accompanying drawings forming a part of this specification, and upon which,

Fig. 1 shows a perspective view of my improved form of pocket knife;

Fig. 2 is an edge view of the same:

Fig. 3 is aback view as seen from the opposite side of that shown in Fig. 2;

Fig. 4 shows a side View of the same knife with the blade in open position;

Fig. 5 shows an end view as seen from the near end of Fig. 1;

Fig. 6 shows a side View of the knife illustrating a slight modified form of wire handle, and

Fig. 7 shows a further side view of knife including a simplified feed form of handle.

As before suggested the handle is formed throughout of a single piece of heavy wire, that is bent and shaped to form a handle which i'ncludes opposite sideportions and a:

yieldablef'ol' spring back er, said p arts being suitably proportioned and spaced apartto form a pocketin which the knife blade is piv'otally supported.

Owing tomy novel design of, a one-piece handle as above outlined, it will be noted that it is possible to form my pocket knife: of but three piecesincluding the small rivet and'that the knife so formed willinclude the important "features found in pocket knives,

of this class, Inthis respect it will be noted that the blade may-be of usual construction and'that thehandle embodies a springback.

and is shaped'toform the required housing for the blade which is operatively mounted in the handle through the medium of a single I l f rivet forming the pivot for the blade';' This handle or housing isformed from a single piece of wire'of suitable length, preferablyfolded midway of its length as at 8 forming a closed loop spring end and disposing the two correspondingly"shaped side members side. by side. These corresponding side members of the one-piece wire handle each comprise a straight back or.

spring member' end loops 10 and side member 11, said side member being bent inwardly to form finger pockets 12 to permit, free'engagementof: the blade for opening the same. The spring members 9 are dis posed against each other toform a knife back and spring for the blade, and loop ends being closed and shaped to form acornmon bearing surface uponwhich the edge ofthe blade operates in a way to prevent the same from wobbling. a w

These side members are spaced apart one from the other so as to form between them a chamber or pocket 14: which is preferably wider at its forward end than at the loop end 10 so as to readily receive the knife blade 15, one end of which is pivotally mounted in the end portions 16 0f the side member of the knife handle as is clearly shown in Fig. 2. The end portions of the side member are preferably flattened as shown and are thus formed flush with the inner face of the wire of the side portions so as to provide a rigid support for the pivotal end of the blade. This end of the blade is pivotally mounted between these end portions of the side memtions 16 of the side members of the handle may if desired be returned slightly as seen in Figs. 1 and 4 or extended in further as shown at 17 in Fig. 6' to form fillings in the side members to better protect'the fingers of the users from the edge of the blade in closing the same and further to. form a protection of the blade itself against foreign objects which may be otherwise brought into engagement therewith,

Itfivill be seen. that the blade designated 18 may be of the usual or any preferred construction, one end being pivoted to a rivet secured in the. end portions of the two side portions of; the handle,the edge portion be-- ing positioned between the tivo side members when the blade is closed. The blade further includes the usual squares at pivotal end of the blade, including the back square a, the run up I), tangend 0 and front square (Z, all of hich are engaged at times by the end 8 of spring back, members 9' to.

hold the blade in its several positions.

Having thus described my inventiomwhat I claim and desire to secure by Letters Patent is 1. A pocket-knife comprising a handlemember and a blade member, the handle member being made of a single piece of Wire fiolded together to form a spring backhaving a closed loop. end for the engagement of the and disposed side members forming the handl'e including tWo adj acently positioned Wire ends having opposed flat and broadened faces,"a straight pivotal stud mounted in and at a right-angle to said faces to suppo t the blade between said flat and broadened faces and against the. said. closed loop end: ofthe spring in a manner to be rigidly supported. 8. A pocket knife including a blade, and a one piece round Wire handle bent to form a closed loop. and spring back and Spaced apart side members having free ends disposed abdjacent the closed loop, end of said spring baek, said closed loop being svvedg'ed together to form a. common bearing surface for the blade, and a pivotal stud mounted in said ends to. support the said blade.
